The objective of this project is to develop and demonstrate cost effective, state of the art CO2 emissions control technologies by treating the flue gas after its combustion in air. The post combustion CO2 capture technologies of this nature are needed to help Canadian industry cope in a transitional marketplace where nearly complete replacement of existing and partially paid-off capital infrastructure with other competing capture technologies may be risky and costly.
Currently the technology is being evaluated for modular design and manufacture and for a number of international projects at commercial scale.

The objective of the project is to address one of the major technical hurdles facing the widespread adoption of integrated gasification combined cycle (IGCC) for power production - low gasifier availability. At present IGCC plants have average availabilities of 85% for power production. This availability is unacceptable to a large number of electrical power utilities, power regulators, and consumers. Low availability translates into an increased cost for power production and/or the need for backup power plant.
Gasification technology has been identified as one of the most promising methods of reducing CO2 emissions. Novel integrated gasification concepts with carbon dioxide capture could potentially result in electrical power production efficiencies as high as 65%. These concepts generally involve gasification, advanced shift reactors, multi-pollutant capture operations, and electrical power production operations (steam turbines, gas turbines, fuel cells. etc.). This work is targeted to provide improved technology for western Canadian feedstocks to improve the business case for the construction of a demonstration gasification plant showcasing clean coal, hydrogen and electrical power production in Canada.
The ITC is a $14 million facility established in 1999 at the University of Regina to develop amine-based technologies to capture carbon dioxide from flue gases from large industrial facilities such as refineries or coal-fired electrical generating stations. ITC has developed world-class post combustion carbon dioxide capture technology using amines.
ITC is working to reduce the cost of these technologies to ensure that they are cost competitive with other emission reduction technologies and that captured carbon dioxide is cheap enough to be used for industrial purposes such as enhanced oil recovery. The ITC’s research has attracted significant industry sponsorship from around the world and has achieved significant reductions in the cost of separating carbon dioxide from the flue gases of electricity generation stations.
ITC research ranges from fundamental studies through amine and process design and demonstration. It operates technology-neutral pilot plants for testing not only amine-based capture technologies developed in-house, but also those developed by external companies and organizations. A wide array of analytical equipment allows the experts at ITC to fully analyze and characterize the capture solvents, processes, and products and to develop solutions to problems such as process efficiency, amine degradation, and corrosion control. The analytical equipment, laboratories, and expertise make ITC one of the most advanced research facilities in North America.

The state-of-the art in CO2 separation is packed bed absorption with aqueous amine as absorbing solvent. The application of current technologies for separating and capturing CO2 from flue gases has been proven to be expensive. Considerable work is being conducted focusing on improvement of existing processes specifically for carbon dioxide capture. These efforts can be summarized as: 1) improving the gas-liquid contact surface area; 2) improving the absorbing liquid formulation to increasing reaction kinetics and decreasing reaction heats; and 3) process optimization.
Development of a technology using a micro-porous hollow fibre membrane module as gas-liquid contactor to achieve efficient low cost CO2 capture from flue gas for CBM and other application.
Initiate the application of this technology for post-combustion CO2 capture from flue gas (a), and the pre-combustion gas cleaning from natural gas (b).
Engage the potential of incorporate this technology with current available liquid absorption processes.

This proposed research work will explore the use of the radical shower plasma generating technology as a flue gas cleaning technology prior to an amine reactor as an effective control technology to remove SO2, NOx and Hg from the coal-fired flue gas. This technology has been identified as a cost effective method to clean flue gas by the utilities.
In this program a plasma radical shower reactor will be designed and tested on a coal-fired flue gas stream to obtain the radical shower plasma multi-pollutant control performance versus the operation conditions such as flue gas temperature, plasma discharge voltage and reagent amount.
Amine-CO2 scrubbing technology is one of the technologies being developed and evaluated as a future CO2 mitigation technology platform by Canadian Power Utilities. To achieve acceptable performance from the amine-CO2 scrubbing technology, the pollutants in the flue gas, such as SO2 and NOx, must be removed prior to the amine reactor in order not to diminish the effectiveness of the amine solution.
The majority of current combustion technologies for fossil fuels result in the emission of copious amounts of carbon dioxide, water vapor, and other pollutants such as oxides of nitrogen and unburned hydrocarbons. All of these emissions, with the possible exception of water vapor, are emerging as threats to the long-term health of the planet. The "Zero Emission Oxy-Fuel Technologies for Clean Fossil Fuels" is focused on developing new and enabling technologies and research infrastructure that could be utilized to reduce GHGs and other pollutants in general, and CO2 in particular, of fossil combustion systems to near zero in short/medium range and to zero in long range. This would be complemented by the production of useful industrial by-products or benign discharge of solid and liquid wastes to land and water.
The primary focus of this project will be geared to the development of the "second generation" of zero emission, oxy-fuel combustion technologies for natural gas, oil and coal that will have higher efficiency and significantly lower capital and operating costs.
